. My invention'relates to boilers and particularly to boilers which are providedy with means for superheating the steam generated therein.-

Y A particular object of the invention is to provide improved superheater apparatus adapted to be built in a j part thereof. i

f characters indicate boiler as a component Many other objects and advantages of the construction herein shown and described will be obvioustoy those skilled in the art from the v disclosure herein given.

To this'end my invention consists in the novel'construction, arrangement and combination of and? more claims: v

VIn the drawings, wherein like reference like or corresponding particularly pointedV out in the parts: y

Fig. 1 is a vertical longitudinal section i taken from a boilerv which embodies the in- Y vention;

Fig. 2 isa section taken on line 22 of 4 is a section takenvon line 4 4 of' Fig. 1 1

In the drawings, I have shown my invention embodied in a boiler of the type more fully shown and described in my copending i application, Serial No. 116,856, filed June 18,

" sitioned in the'lower vis connected to the 1926, but it is to be understood that I am limited to this construction only to the extent indicated in the appended claims.

Y In ythis instance, the boiler comprises a setting v1 which is provided with a combustion chamber 2. Disposed in the upper end of the setting 1 are steam and water drums 3 and 4, the drums 3 and 4 being positioned at substantially the same elevations and the drum 4 being positioned atthe front of the setting. At 5, I haveshown a mud drum which is popart of the settingI 1 and drums 3 and 4 through banks of tubes 6 and 7, respectively. Disposed intermediate the'drums 3 and 4 and below them is a drum8 which is connected by tubes 9 to the drum 4. The drums 5 and 8 parts herein shown and described,

communicate with each other through a bank :of tubes 12'and-through a bank of tubes 13. 'i

Positioned intermediate the tubes 12 and 13 a'nd'extendin from the drum 5 to thedrum 8 is a"`wall'orl1atlie 14'and extending downwardly from the drum 3 to a point intermediate the drums 3 and 5 is a wall or baille tile 15. I preferably provide a bank of tubes 17 in -front of the battle 15 which tubes 17 communicate with the drums 3 and 5. In the illustrated embodiment of the invention, aligned bailles 17a and 17 b insure that the 4gasesl of combustion will pass through the bank of tubes 12.

As 'set forth in my above-mentioned cofpen'dingapplication, the drums 3, 5, 8 and 4 are soarranged that a relatively large numberof tubes may be readily positioned there between so that the water ly through the boiler.

ater is admitted to the boiler through the'pipe 35 which extends into the drum 3 and is adapted to discharge the water into a tlrpgh orpan 37 disposed within the drum. skilled in the art. Y

Referring now to Fig. 1, it will be noted that have provided achamber 2O within thel drum 4, the chamber 20 being formed by a substantially U-shaped wall 21. The chamber 20 does not communicate directly with the interior of the drum 4 but communicates through tubes with the drum 3 and with a header' 24. Thus, I have shown a bank of tubes 26 which connect the chamber 20 with the header l24 and a bank of tubes 29 which connect the chamber 2O with the drum 3. It will be noted that the upper portions of the drums'3 and 4 communicate with each otherl through a bank of tubes 30 and that the uppei yportion of the drum 8 communicates with the may circulate free,-

s Vconstruction is well knownto those As best shown in Figs. l and 4, the tubes 26 and y29 are preferably arranged in groups so A that the' ends thereof that project intoi the chamber 2O arel accessible through handlhole ,Y v openings 39 provided in the wall 21. These openings are normally closed by plates d0.

The operation vof the above describedap-` paratusis substantially asfollowsf; 1 '1 Water is admitted to the boiler through the,Y ,o pipe 35 and circulates through out the drums and tubes. It flows upwardlyin the-tubes 753i and descends through the tubes 6 and 12, The steam generated inthe drum 4 tlows through the tubes 30 tothe drum 3 and 15 thence flows with the steam generated'in' the drum 3 through the tubes 29.to thechamber f y2O after which-.it passesto,the-header '2liV f through-the tubes y26. [Steafin` generated :in or collected bythe drum tlcwsthrough the A '.Uvtubes 3lA to the drum i andithence tothe f drum 3 by way et the tubes 30 which delivers it tothe tubes'29. The tubes 26 andy 2 9 tune-- y tion as a superheater as they vare exposed to y the gasesoicombustion whch flow over/the druinf. i .l f.- V Having thus described my invention, itis obvious that various immaterial modificationsfmay be made in the same without de'- parting from the spirit of my invention; Y ae hence l do notwish to-be -underjstood'as limitt ingnmyselt to the exact term, construction, arrangement andcombinationoi parts herefin shown and described, or usesinentioned.

f VVhat/lclaim as new and desire to secureby sLetters Patent is:` l ;m l.
